so what happens when you test it without the height= and width= parameters?
Its been a decade since I did serious applet stuff

If I remove the width and height tags, then the applet is shown in a 192x192 box. Maybe it's some portion of the window size or just a default size. However, the applet is still bounded in a small box. ;)

Eyes dwelling into the past are blind to what lies in the future. Step carefully.
